1 In isolated pancreatic islets, alloxan almost completely blocked both glucosamine-induced and STZ-induced protein O-GlcNAcylation, suggesting that alloxan indeed was inhibiting (OGT). Alloxan O-linked N-acetylglucosamine (GlcNAc) transferase Homo sapiens
2 In isolated pancreatic islets, alloxan almost completely blocked both glucosamine-induced and STZ-induced protein O-GlcNAcylation, suggesting that alloxan indeed was inhibiting (OGT). Alloxan O-linked N-acetylglucosamine (GlcNAc) transferase Homo sapiens
3 In order to show definitively that alloxan was inhibiting OGT activity, recombinant OGT was incubated with 0-10 mM alloxan, and OGT activity was measured directly by quantitating UDP-[(3)H]-GlcNAc incorporation into the recombinant protein substrate, nucleoporin p62. Alloxan O-linked N-acetylglucosamine (GlcNAc) transferase Homo sapiens
4 In order to show definitively that alloxan was inhibiting OGT activity, recombinant OGT was incubated with 0-10 mM alloxan, and OGT activity was measured directly by quantitating UDP-[(3)H]-GlcNAc incorporation into the recombinant protein substrate, nucleoporin p62. Alloxan O-linked N-acetylglucosamine (GlcNAc) transferase Homo sapiens
5 In order to show definitively that alloxan was inhibiting OGT activity, recombinant OGT was incubated with 0-10 mM alloxan, and OGT activity was measured directly by quantitating UDP-[(3)H]-GlcNAc incorporation into the recombinant protein substrate, nucleoporin p62.

6 Under these conditions, OGT activity was completely inhibited by 1 mM alloxan with half-maximal inhibition achieved at a concentration of 0.1 mM alloxan. Alloxan O-linked N-acetylglucosamine (GlcNAc) transferase Homo sapiens
7 Under these conditions, OGT activity was completely inhibited by 1 mM alloxan with half-maximal inhibition achieved at a concentration of 0.1 mM alloxan. Alloxan O-linked N-acetylglucosamine (GlcNAc) transferase Homo sapiens
8 Together, these data demonstrate that alloxan is an inhibitor of OGT, and as such, is the first OGT inhibitor described. Alloxan O-linked N-acetylglucosamine (GlcNAc) transferase Homo sapiens
9 Together, these data demonstrate that alloxan is an inhibitor of OGT, and as such, is the first OGT inhibitor described. Alloxan O-linked N-acetylglucosamine (GlcNAc) transferase Homo sapiens
